Disinfection effects of Cavi wipes on object surface touched frequently among multidrug resistance infection patients in intensive care unit

Abstract

Objective To explore the disinfection effects of Cavi wipes and chlorine containing disinfectant on object surface touched frequently among multidrug resistance infection patients in intensive care unit. Methods We selected 40 multidrug resistance infection patients with mechanical ventilation in general intensive care unit (GICU) and respiratory intensive care unit (RICU) at Liangxiang Hospital in Fangshan District from June 2016 to May 2018 by convenience sampling. All of the patients were randomly divided into control group (object surface disinfection by 500 mg/L chlorine containing disinfectant) and experimental group (object surface disinfection by Cavi wipes) . We carried out sampling and bacterial culture in object surface touched by patients frequently both groups (right bed handrail, ventilator panel parameter key and infusion pump on/off key) before, 5 minutes, 6 hours and 8 hours after disinfection and monitored the target drug-resistance bacteria. Results Before disinfection, there were no statistical differences in the bacterial culture results of object surface touched frequently in patients between two groups (P>0.05) . After disinfection, the bacterial colony counting of object surface touched frequently in patients between two groups was lower than that before with statistical differences (P<0.01) . The colony counting 8 hours after disinfection of experimental group were lower than those of control group with statistical differences (P<0.05) . Conclusions Cavi wipes and 500 mg/L chlorine containing disinfectant all have good disinfection effects. Disinfection effects of Cavi wipes in bed and other object surface touched frequently are better than those of chlorine containing disinfectant which is convenient and is worthy of being widely used in clinical application.
